PROTECTOR FOR MECHANISM.

Specification of Letters Patent.

Patented Apr. 2%, 1919 Application filed November 9, 1918. Serial No.261,894.

for Mechanisms, of which the following is a specification.

The object of my invention is to provide a simple, cheap and effectiveprotector or guard adapted to protect operatives from power drivenshafts, motors and the like K used for operating machinery.

My invention has particular reference to protectors or guards adaptedfor use with sewing machine tables and to be interposed between a powerdriven shaft and motor beneath the table and the operative sitting infront of the tab-1e.

In carrying out my invention 1 provide a frame adapted to be securedbetween the table top and the floor in front of the power driven shaftand driving motor beneath the table top, which frame is provided with aslidable protecting member adapted to be moved to one side to permitaccess to the driving belt, shaft, etc., said frame also having anotherprotecting member cooperative with the first named member as a permanentshield in front of said shaft or motor.

My invention also comprises novel details of improvement andcombinations of parts that will be-more fully hereinafter set forth andthen pointed out in the claims.

Reference is to be had to the accompanying drawings forming a parthereof, in which Figure 1 is a perspective View of my improvements inconnection with a sewing machine table; Fig. 2 is an end view of Fig. 1;Fig. 3 is an enlarged section substantially along the line fi -3 in Fig.1; and Fig. 1 is an enlarged detail along the line 4-4: in Fig. 3.

Similar numerals of reference indicate correspondingparts.

In the accompanying drawings the numeral 1 indicates a sewing machinetable shown having a top and legs of any suitable construction, adaptedto support a single sewing machine 2, although the table may be ofconsiderable length having mounted thereon any desired number of sewingmachines spaced apart in the usual manner. At 3 is indicated a powerdriven shaft wh1c h may be driven by a motor 4, wlnch shaft is providedwith a power driving pulley 5.

Said shaft andpulley are adapted for a table for a single sewingmachine, as illustrated,

or the shaft may extend lengthwise along a table upon which severalsewing machines are applied, and pulleys 5 may be upon said shaft forall such sewing machines. A belt 6 extends from the pulley 5 to 'asuitable transmission mechanism-7, shown supported beneath the table topto receive thebelt '8 for operating the sewing'machine in the usualmanner. A treadle Wbymeans of suitable connections is controlledtooperate the transmitting mechanism 7 in .well known manner. Beneath thetable top in front of the shaft 3 and'the mot or,-' and shown betweensaid shaft and transmission mechanism 7, is an open frame shown-co nprising spaced upright bars 9 and horizom tal bars 10 secured togetherin a rectangular manner, as by rivets 11. The upper and lower ends ofthe vertical bars '9 are shown bent laterally at 9 forming feet-whichmay be secured respectively to the floor 12 and to the under side of thetable top by screws for rigidly securing the said frame in place. At 14is a protecting member or wall mounted upon bars 10 of said frame, andshown in the form of a metal plate having its upper and lower edges 14folded to receive said bars, which plate may be secured in a fixedposition upon said frame by rivets, which may be the rivets 11 thatsecure the bars 9 and 10 together. At 15 is a protecting memher or wallmounted slidably upon said frame and shown in the form of a metal platehaving its upper and lower edges 15 folded in groove-like form andreceiving the upper and ower edges of the member 14; and

the horizontal bars 10, whereby one edge portion of member 15 normallyrests on the adjacent portion of member 14 to slide thereon and the mainportions of the folded parts 15 receive and can slide along. thehorizontal bars 10. A handle 16 may be provided upon the member 15 foroperating the latter. Upon a bar 10 I preferably provide a stop 17 whichmay be in the nature of a bolt adjustable in alongitudinal slot 18 insuch bar 10, whereby said bolt may be set at a desired position toobstruct movement of member 15 toward belt 6, to retain the ad jacentedge of said member out of contact with said belt and yet near the same.The position of the member 15 will be such that it may be slid to oneside along the frame parts 1O, 14 with its edge adjacent the belt 6, asshown in Fig. 1, in front of the power shaft and the motor, and mayslide along in the other direction to uncover the space between theright hand edge of the member 14 and the belt 6 to permit access to saidbelt for adjusting it as well as to the motor. When the parts are in theposition shown in Fig. 1 the members 14, 15 overlap at adjacent ends andare spread to extend along the bars 10 in a position to provide acomplete protector or shield between the operative sitting in front ofthe table and the power shaft and motor. The lower bar 10 and themembers 14, 15 are illustrated at such height as to provide spacebeneath to permit ready sweeping of the floor below the table.

The frame having bars 9 and 10 and members 14, 15 may be made insuitable dimensions to be individually applied beneath the table whetherthe latter be adapted for a single sewing machine and operator, or be ofextended length for a plurality of machines and operatives.

The protector is simple, cheap in construction, adapted to bereadilyapplied, efficient in use in preventing the clothes of the operativefrom encountering the drive shaft and motor, and movable member 15, isreadily operable to permit access to the drive shaft, motor and thelike.

Having thus described my invention, what I claim and desire to secure byLetters Pat ent is:

1. A protector for mechanism, comprising a frame having spacedhorizontal bars and spaced upright bars secured together and adapted tobe secured between a table top and a fioor, and a protecting memberslidably mounted upon said horizontal bars.

2.
